Benadryl Allergy Relief

Benadryl is one of the world's most recognized names in allergy relief. Its origins date back to the mid-1940s when the antihistamine diphenhydramine was developed by George Rieveschl while working at the University of Cincinnati. It was subsequently launched commercially by the pharmaceutical firm Parke-Davis.

Over the decades, the brand has undergone several changes in ownership through corporate mergers and acquisitions. For a long period, it was part of the Pfizer Consumer Healthcare portfolio until many of Pfizer's over-the-counter brands were acquired. Today, Benadryl is owned by Kenvue, a dedicated consumer health company that officially spun off from Johnson & Johnson.

Manufacturing for Benadryl occurs in multiple countries, including the United States, Canada, and various European nations, depending on the specific product formulation and regional market. Despite the change in parent company ownership to Kenvue, the brand maintains its legacy as a cornerstone of allergy treatment globally.
